Effect of AsA and X- radiation on THP-1 cells lines ‘colonies formation. (a) Colony formation images, stained with 0.01% crystal violet for 1 h, only the cells with a diameter greater than 50 μM that were counted. (b) The bar chart of the number of the of THP-1 colonies. (c) The survival fraction of the THP-1 colonies normalized to the plating efficiency of the untreated control cells.
